Highly Regio- and Stereoselective Synthesis of Multialkylated Olefins through Carbozirconation of Alkynylboronates and Sequential Negishi and Suzuki-Miyaura Coupling Reactions
摘要：
Two Nobel couplings: The synthesis of tri- and tetraalkylated olefins has been achieved (see scheme). These multialkylated olefins were prepared by the zirconocene-mediated carbometalation of 1-alkynylboronates and subsequent sequential CC bond formation with Negishi and Suzuki–Miyaura cross-coupling reactions using β-hydrogen-containing alkylzinc reagents and alkyl electrophiles as coupling partners.
